It features a specially designed 18\" woofer with a 5\" voice coil, allowing for wide linear excursion (±15 mm).\u003c\/p\u003e\n\u003cp\u003eThrough ventilation at the pole core, heat generated by the voice coil is optimally dissipated, thus enabling a high power handling capacity of 1800 W\u003csub\u003eRMS\u003c\/sub\u003e and 7200 W peak. Lower heat generation also means increased reliability and reduced thermal stress on the voice coil; the result is excellent dynamics and a dry, controlled bass reproduction at an incredible sound pressure.\u003c\/p\u003e\n\u003cp\u003eIt does not have an internal passive crossover, so frequency cutoff must be performed by Harmonic Design system power amplifiers or an external electronic crossover; up to a maximum of 160 Hz (with a 24 dB\/oct slope), it ensures the best possible transitions between subwoofer and satellite.\u003c\/p\u003e\n\u003cp\u003eThe cabinet is made of high-quality multilayer wood, painted to be scratch, impact, and weather resistant with a finely textured polyurea finish. Two ergonomic transport handles on the top ensure easy handling. There are also threads for attaching hd SilentWheels, the special acoustically decoupled 100 mm wheels. An M20 threaded insert on the top of the cabinet allows for mounting a pole to attach another loudspeaker. The hd Sub18 is also available in an installation version without handles and M20 thread.\u003c\/p\u003e\n\u003cp\u003eIt can be used as a slave subwoofer in addition to the hd P18 stereo active subwoofer or with all Harmonic Design system power amplifiers to ensure reliable and accurate low-frequency reproduction.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey features\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\n\u003cli\u003e1 x high-performance 18” subwoofer (1800 W \/ 7200 W)\u003c\/li\u003e\n\n\u003cli\u003eFrequency response from 35 Hz\u003c\/li\u003e\n\n\u003cli\u003eMax SPL 143 dB\u003c\/li\u003e\n\n\u003cli\u003eThis model includes a rigging frame for line array configuration\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\u003ch3\u003e\u003cstrong\u003eSPECIFICATIONS\u003c\/strong\u003e\u003c\/h3\u003e\u003cul\u003e\n\n\u003cp\u003e\u003cstrong\u003eTechnical characteristics\u003c\/strong\u003e\u003c\/p\u003e\n\n\u003cul\u003e\n\n\u003cli\u003ePrinciple: bass-reflex system\u003c\/li\u003e\n\n\u003cli\u003eTransducers: 1 x 18″ long excursion woofer with a 5″ voice coil, vented at the pole piece and spider\u003c\/li\u003e\n\n\u003cli\u003eCrossover: active up to a maximum of 160 Hz\u003c\/li\u003e\n\n\u003cli\u003ePower handling: 1800 W\u003csub\u003eRMS\u003c\/sub\u003e \/ 7200 W peak\u003c\/li\u003e\n\n\u003cli\u003eFrequency response: 35 – 160 Hz\u003c\/li\u003e\n\n\u003cli\u003eSensitivity: 102 dB\/W\/m\u003c\/li\u003e\n\n\u003cli\u003eSPL max: 143 dB (half space)\u003c\/li\u003e\n\n\u003cli\u003eNominal impedance: 8 ohm\u003c\/li\u003e\n\n\u003cli\u003eEnclosure: 18 mm multiplex birch wood, baffle 36 mm multiplex birch wood, polyurea plastic coating black, steel grille coated, acoustic foam, 2 transport handles, prepared for 100 mm hd SilentWheels, M20 thread insert\u003c\/li\u003e\n\n\u003cli\u003eConnections: 2 x speakON NL4\u003c\/li\u003e\n\n\u003cli\u003eDimensions: 536 x 542 x 600 mm\u003c\/li\u003e\n\n\u003cli\u003eWeight: 40 kg\u003c\/li\u003e\n\n\u003cli\u003eOptions: transport protection cover, wheelboard, installation version, weather protection and RAL color customization\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n\n\u003c\/ul\u003e","brand":"Harmonic Design","offers":[{"title":"Default Title","offer_id":54311864107341,"sku":"60026","price":3246.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/0643\/6173\/files\/36759_60026_big.jpg?v=1784203822","url":"https:\/\/musicdelivery.net\/en\/products\/harmonic-design-hls-sub18","provider":"Music Delivery","version":"1.0","type":"link"}
